5042-H19 Aluminum

5042-H19 aluminum is 5042 aluminum in the H19 temper. To achieve this temper, the metal is strain hardened to a strength that exceeds H18 by at least 10 MPa (or 1.5 ksi). The graph bars on the material properties cards below compare 5042-H19 aluminum to: 5000-series alloys (top), all aluminum alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
